Going to bed for a 5:57 am alarm

Asleep by 8:42 pm — 6 full sleep cycles, about 9 hours
Asleep by 10:12 pm — 5 full sleep cycles, about 7 hours
Asleep by 11:42 pm — 4 full sleep cycles, about 6 hours

A sleep cycle runs about 90 minutes, and most people take around 15 minutes to drop off. Waking at the end of a cycle feels easier than waking in the middle of one.

How to use the online alarm clock

As you finish the last indoor job and head out to let the hens into the yard after dawn, an alarm for 5:57 am gives you a clear cue to leave. It falls just before 6:00 am, so you can put away what you are using, pull on your wellies and collect anything needed for the poultry run without drifting into another task.

For this particular alarm, check the sound setting before relying on it: silent mode can leave the alert unheard even when the time has been set correctly. Choose an audible volume and make a quick test if others are still asleep nearby. Keep the browser running and the screen awake until 5:57 am; otherwise the alert may not sound and the hens could be kept waiting indoors beyond your planned release.

Once you step towards the hen house, notice whether the early air feels damp rather than judging conditions through the kitchen window. Moisture can linger on grass, latches and wooden ramps after a cool British night, even when dawn looks bright. Keep a dry cloth by the door for a wet catch, and tread carefully across slick paving while opening the run.

Common questions

Can I use this on a phone?

It works in a mobile browser, but phones lock the screen and suspend background tabs far more readily than a laptop does, which can stop the alarm sounding. For anything important, a desktop or a plugged-in laptop is the steadier option.

Does the alarm still work if I close the tab?

No. Everything runs inside this page, so closing the tab — or quitting the browser altogether — ends the countdown there and then. Leaving it open in the background is all it asks, and switching to another tab makes no difference.

What happens if my laptop goes to sleep before 5:57 am?

The tab sleeps along with it and the alarm will not sound on time, if at all. If you are relying on it, change the power settings so the machine stays awake, or keep a phone alarm running as well.

Do I need an account or an app?

Neither. Choose a time and a sound, press Start, and it runs in this browser tab. Nothing is downloaded, nothing is registered, and closing the page leaves nothing behind on the device.
